Abstract
Sivelestat sodium hydrate is a selective inhibitor of neutrophil elastase, which is effective in acute lung injury associated with systemic inflammatory response syndrome. However, the effectiveness of sivelestat in sepsis has not been fully examined. In the present study, the effect of sivelestat on severe sepsis in a rat cecal ligation and puncture (CLP) model was investigated. Adult male Sprague-Dawley rats underwent CLP and were randomly divided into two groups: sivelestat-treated group and saline-treated controls. The serum concentrations of several inflammatory mediators were measured. Hematoxylin-eosin staining, and immunohistochemical staining for high-mobility group box chromosomal protein 1 (HMGB1), IL-8, and CD68 were performed on the lungs to assess pathological changes found 12 h after the CLP procedure. Treatment with sivelestat significantly improved the survival rate of the post-CLP septic animals (P = 0.030). Sivelestat also induced a significant reduction in serum IL-1β (P = 0.038) and IL-10 (P = 0.008) levels in these CLP rats. Serum HMGB1 levels had no significant difference between the sivelestat-treated and the control group. The lungs from sivelestat-treated rats exhibited less severe pathological changes and decreased the numbers of HMGB1, IL-8, and CD68-positive cells (P < 0.001). Sivelestat significantly improved survival rate of rats with clinically relevant sepsis, possibly by attenuating sepsis-induced systemic inflammatory response and lung injury. This may explain the implicated health benefits of sivelestat in reducing morbidity and mortality from sepsis.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
